According to a new study, women who wear a U.K. size 14 are the happiest with their life and looks.

One quarter of women who wear a size 14 (equivalent to a U.S. size 12) said they were extremely happy with their lives, more than any other dress size, according to a study by Special K. Women who are a U.K. size 24 are the least happy, but the survey found that happiness did not correlate to size, as the fourth least happy size was a 6. Though 12, 14, and 16, were among the happiest sizes, of the 3,000 women surveyed, 48 percent still said they were not happy with their weight. [The Telegraph]
